@Lustig Andrei,
It is not just something one knows but something one
does. Einstein, recognized his work General Relativity (and now it's newest off-spring, M-Theory) merely for it's beauty and elegance.
However, I understand your point.
You're suggesting that in science and any work(s) from that field are meant to be reproducible to anyone who follows the same pathway of experimentation, whereas in Art, that simply is not the case, as Art is to be considered 'unique' to that Artist. But isn't a new hypothesis and theory an art in itself - an artistic representation of another artwork (previous hypothesis and theory)?
Also my idea of art is as a matter of intention- to capture understanding or to mimic nature.
Fil Albuquerque:
There is good art and bad art, and this "good" and "bad" is a similar problem with science. There are the scientists who takes little time to decide on a theory, then do not listens to anyone concerning their findings. Then there are the scientists who will spend a long time to correctly and accurately represent what it is they have found in nature.

I suppose in the end it is all a matter of various ways each individual sees a word.
It'd be interesting to hear from any artists, and I wonder if they would balk at the comparison.
